BOTTLE CAP.

Application filed March 31', 1924. Serial No. 703,149.

This invention relates to improvements in bottle stoppers, and more particularly to milk bottle stoppers of that type consisting of a cardboard disk.

The invention has for its primary object the provision of a milk bottle stopper of the character stated which may, without danger of being displaced from bottle sealing position, be readily punctured to provide a vent opening and an opening through which a drinking tube may be inserted into the bot tle, whereby to permit the contents of the bottle to be readily consumed without removing the stopper.

With the above and other objects in view, the invention consists in a construction, com bination and arrangement of parts herein after fully described and claimed. and illustrated in the accompanying drawing, where- 1n:

Figure 1 is a top plan view of a milk bottle provided with a stopper embodying my invention,

Figure 2 is a sectional view taken on the plane indicated by the line 22 of Figure 1,

Figure 3 is a detail top plan view of the stopper, and

Figure 4 is a detail sectional view of the stopper taken on the plane indicated by the line 3-43 of Figure 3.

Referring to the drawing by reference numerals, 1 designates the upper portion of a milk bottle of a well known construction. At its upper end the bottle is provided with a flange 2 and a shoulder 23, the latter forming a seat or rest for the stopper 4: which is retained in place against accidental displacement by the overhanging portion 5 of the flange 2.

In carrying out my invention. the stopper 4, which is in accordance with the present practice made of paraiiined' cardboard, is provided with relatively spaced recesses 6 opening out through the upper side thereof. The recesses 6 are located adjacent the edge of the stopper 4 in diametrical alinement. their side walls are inclined upwardly and outwardly, and their depth is approximately equal to one-half the thickness of the stopper 4. The recesses 6 are preferably formed during the formation of the stopper 4 by compressing portions of the material from which the stopper is made, and this is done in a manner to leave the inner or under surface of the stopper 4: unbroken or smooth. To permit the formation of the recesses 6, the die employed in striking up the stopper 4 from the stock, may be provided with projections or lugs similar in outline to the formation of the recesses.

From the foregoing description, taken in connection with the accompanying drawing, it should be apparent that the recesses 6 provide the stopper 4 with two comparatively weak circular portions which may be readily struck out to provide a vent opening and an opening through which a drinking tube may be inserted into the bottle. As the contents of the bottle may be consumed without removing the stopper 4, there is no danger of spilling the contents and the liability of the contents being contaminated is reduced to the minimum. While the bottom walls of the recesses 6 may be readily struck out, they cannot, due to their density resulting from the compression of the disk material to provide the recesses and to their location within the plane of the stopper and below the upper surface thereof, become accidentally ruptured during the application of the stopper to the bottle. It should also be apparent that said circular port-ions permit a pointed instrument to be readily passed through the stopper when it is desired to remove it from the bottle in order that the contents may be poured into a glass, pitcher or the like. As is apparent, any suitable implement may be employed to strike out the bottom walls of the recesses 6. -While I have shown my invention embodied in a milk bottle stopper of disk formation, it is to be understood that it may also be embodied in milk bottle stoppers of that type comprising a paper cap adapted to fit over and about the upper end of the bottle and be secured in applied position by a ring.

It should be further understood that the drawing is merely illustrative and does not pretend to give exact proportions.

What is claimed is 1. A stopper for bottles of paper material and of substantially uniform thickness throughout, a portion of said material hav- 5 ing been condensed Without rupturing or striking out the surface thereof, and said portion being adapted to be pierced to provide the stopper with an opening.

2. A stopper for milk bottles of paper material and of substantially uniform thickness throughout, having a condensed portion located Wholly within the plane thereof and adapted to be pierced to provide the stopper with an openin In testimony whereof I affix my signature.
